Answer:
(E) None of the above
Step-by-step explanation:
The statistic provided is that of the population but the statistic you seek is that of the sample.
Looking at the statistic itself, Variance is the square of Standard Deviation or standard deviation is the square root of variance.
Hence you calculate the standard deviation of the population mean:
√144 = 12
The population standard deviation of/from the mean value is 12.
It could be possible to decipher the sample mean from population mean but not sample size.
So, you can't pick just any answer. Population size should be given first.

We know that,
Using this rule, we get the factorizations of the given exponents and their values.
Answer:
The special features of a polynomial graph are sharp corners but in these types of graphs it also has smooth curves. Polynomial graphs functions also display graphs that have no breaks.Curves with no breaks are called continuous.
Step-by-step explanation:
Answer:
length = 20 cm
width = 9 cm
Step-by-step explanation:
perimeter = 58 cm
58cm = 2*L+2*w equation 1
L = 3w -7 equation 2
where:
L= length
w=width
so we have:
58 = 2(3w -7) +2w
58 = 6w -14 +2w
58 +14 = 8w
72 = 8w
w = 72/8
w = 9 cm = width
we have:
L = 3(9) -7 = 20 cm = length
